If it's a webforms project (not MVC) and you don't want to use AJAX, you can use __doPostBack.

C#:

public void Page_Load(object sender, EventArgs e)
{

  var senderObject = Request["__EVENTTARGET"]; // func
  if(senderObject == "func")
  {
     //call your function here, or write the implementation
  }
}
